Legend:
Speech characteristics of nonfluent-variant primary progressive aphasia (red), logopenic-variant primary progressive aphasia (blue), semantic-variant primary progressive aphasia (purple), behavioral-variant frontotemporal dementia (green), progressive apraxia of speech (yellow), and primary progressive apraxia of speech (brown). Speech characteristics were included where more than 80% of studies which tested that measure found a statistically significant difference from a healthy group. PVI = pairwise variability index; MSR = maximum speech rate.
